Maximum amount of concurrent connections is already used #22

Closed sametserpil closed 2 months ago

sametserpil commented 2 months ago

Hello friends,

I have an office with knx infrastructure and an automation software runs on it. I have 2 knx ip router devices and one of them is broken. I want to use this project as a replacement to that broken knx ip router. ETS can recognize calimero server but when I test it it says "The interface can not accept the new data connection because its maximum amound of concurrent connections is already used"

Here is the console output:

Could you please help me?

In the server configuration, under <additionalAddresses>, add some more addresses. This will help. Also, I see in the log output, that you try to connect the subnet link <knxSubnet ... to the server itself? Because both the server and the configured subnet connection do have the same IP and port. Which wouldn't make sense.

sametserpil commented 2 months ago

Adding some more addresses fixed connection problem. However, I din't understand how to configure knxSubnet.

<knxSubnet type="virtual" medium="tp1" >virtual-subnet</knxSubnet>

does this makes sense?

Oh, I've just figured it out. Thank you. This pproject is awsome.
